The Cormack-Lehane system classifies views obtained by direct laryngoscopy based on the structures seen.

Use

Use to describe the structures visible during direct laryngoscopy and indirectly to indicate the likely difficulty of laryngeal intubation.
The position of the head and other relevant information will be carried in other relevant ENTRY archetypes.

Misuse

Not to be used for recording Modified Cormack-Lehane grading (Yentis & Lee, 1998). Use a specific archetype for this purpose.

Purpose

To describe the structures visible during direct laryngoscopy and indirectly to indicate the likely difficulty of laryngeal intubation.
